I tried today with dialogue audio of 1 hour, using auto split as specific time intervals, it didn’t really work, when I joined them back together, the start of each segment joined back up were jumpy. However, what did work was, I created 10 segments with region markers manually and timed the markers to where a person took a pause of silence, used auto split, put the split files into a batch for sonic treatment, then rejoined the files. it took 2 minutes to complete rather than 14min for the entire hour. I definitely think with these massive core counts there is something there to work within some way that could massively reduce render times, well, in the dialogue world anyway…
